First, the control that the suppression blade drive division 25a to the left when lobus sinister sheet 23a blade drive division 25a to the left rolls oblique condenses is described.Fig. 5 (a) is the figure of the wind direction change state representing lobus sinister sheet 23a.Lobus sinister sheet 23a shown in Fig. 5 (a) is from frontal angle of inclination X1 to the left.It addition, illustrate only the lobus sinister sheet 23a being positioned at the leftmost side in Fig. 5 (a), but the whole lobus sinister sheet 23a linked by left connection shaft 24a carry out identical rotational action.
When after the lobus sinister sheet 23a shown in Fig. 5 (a) rotates, when proceeding for blowdown firing under conditions of easily condensation, from the inside of indoor set 1 towards the cold air of frontal blocked by lobus sinister sheet 23a and towards left direction.Like this, cold air is flowed in the casing of indoor set 1 by through hole 26a, causes cooling down lobus sinister sheet drive division 25a.Then, condensation is produced at lobus sinister sheet drive division 25a.
Then, in the present embodiment, when becoming the condition of easily condensation, the rotation in the lobus sinister sheet 23a direction that blade drive division 25a is configured to the left (direction i.e. opened) is limited from the frontal of indoor set 1.Hereinafter enumerate object lesson to illustrate.
In the present embodiment, as becoming the condensation condition deciding whether to limit the condition of the rotation of lobus sinister sheet 23a it is, for supplying blowdown firing and indoor humidity to be more than the humidity specified.Such as, in the case of detecting that indoor humidity is more than 70% in for blowdown firing, it is judged that the condensation condition of regulation is set up.It addition, the condensation condition of present embodiment is an embodiment, such as, can also add the condition of more than the indoor temperature that indoor temperature is regulation, or the condition of extraneous gas temperature that outdoor temperature deficiency specifies.Additionally, in the case of being not provided with humidity sensor, it is also possible to the establishment of condensation condition is only judged by indoor temperature, outdoor temperature.
In the case of such condensation condition is set up, limit in the way of suppressing the maximum of the rotation of lobus sinister sheet 23a.That is, the angle that lobus sinister sheet 23a rotates to the side being configured with lobus sinister sheet drive division 25a is restricted to below the angle of regulation.
Fig. 5 (b) is the confined state diagram of rotation of lobus sinister sheet 23a.The lobus sinister sheet 23a of rotational angle X1 to the left shown in Fig. 5 (a), in the case of the condensation condition of satisfied regulation, as shown in Fig. 5 (b), is restricted to rotational angle X2 (angle X1 ＞ angle X2) the most to the left.It addition, angle X2 is the angle determined beforehand through experiment etc., can suitably change according to the position etc. of through hole 26a.
It is explained above lobus sinister sheet 23a, but lobus dexter sheet 23b is also same.Then, illustrate that lobus dexter sheet 23b blade drive division 25b to the right rolls the control of the suppression condensation of oblique state.
Fig. 6 (a) is the figure of the wind direction change state representing lobus dexter sheet 23b.Lobus dexter sheet 23b shown in Fig. 6 (a) is from frontal angle of inclination X1 to the right.It addition, illustrate only the lobus dexter sheet 23b being positioned at the rightmost side in Fig. 6 (a), but the whole lobus dexter sheet 23b linked by right connection shaft 24b carry out identical rotational action.
In the case of the condensation condition of regulation is set up, as lobus sinister sheet 23a, limit in the way of suppressing the maximum of the rotation of lobus dexter sheet 23b.That is, the angle that lobus dexter sheet 23b rotates to the side being configured with lobus dexter sheet drive division 25b is restricted to below the angle of regulation.
Fig. 6 (b) is the confined state diagram of rotation of lobus dexter sheet 23b.The lobus dexter sheet 23b of rotational angle X1 to the right shown in Fig. 6 (a), in the case of the condensation condition of satisfied regulation, as shown in Fig. 6 (b), is restricted to rotational angle X2 (limited angular of regulation) the most to the right.It addition, angle X2 is the angle determined beforehand through experiment etc., can suitably change according to the position etc. of through hole 26b.
As it has been described above, in the present embodiment, when lobus sinister sheet 23a rotates to the side being configured with lobus sinister sheet drive division 25a, for lobus sinister sheet 23a, limit the angle rotated to the side being configured with lobus sinister sheet drive division 25a.Additionally, when lobus dexter sheet 23b rotates to the side being configured with lobus dexter sheet drive division 25b, for lobus dexter sheet 23b, limit the angle rotated to the side being configured with lobus dexter sheet drive division 25b.By such restriction, the amount of the air-flow blocked by lobus sinister sheet 23a or lobus dexter sheet 23b reduces, and the amount of the air-flow therefore arriving lobus sinister sheet drive division 25a or lobus dexter sheet drive division 25b via through hole 26a or through hole 26b also reduces.Thereby, it is possible to suppress the generation of the condensation of vane drive mechanism 25 (lobus sinister sheet drive division 25a and lobus dexter sheet drive division 25b) to the left and right.It addition, in the above description, in the case of angle X1 is less than angle X2, it is not necessary to carry out for suppressing the rotation of condensation to limit.
Then, control when lobus sinister sheet 23a rotates to the opposition side of the side being configured with lobus sinister sheet drive division 25a is described.
Fig. 7 (a) is the figure of the state representing that lobus sinister sheet 23a rotates to the rightabout (being right direction relative to frontal) in the direction being configured with lobus sinister sheet drive division 25a.In Fig. 7 (a), arrow in dash-dot line represents the flowing of air-flow.As shown in Fig. 7 (a), in the air-flow straight ahead of the left side flowing of the lobus sinister sheet 23a being positioned at left end (closest to lobus sinister sheet drive division 25a).Other air-flow flows along lobus sinister sheet 23a to each other at lobus sinister sheet 23a.
As a result, at the lobus sinister sheet 23a of left end, producing air-flow not along the region 71 (shown in dotted line) that this surface current is dynamic close to the face of frontal side.Owing to producing region 71, the two sides temperature difference at the lobus sinister sheet 23a of left end becomes big, therefore condenses.
Additionally, the lobus dexter sheet 23b of right-hand member is also same.Fig. 7 (b) is the figure of the state representing that lobus dexter sheet 23b rotates to the rightabout (being left direction relative to frontal) in the direction being configured with lobus dexter sheet drive division 25b.As Fig. 7 (a), in Fig. 7 (b), in the face close to frontal side of the lobus dexter sheet 23b of right-hand member, produce air-flow not along the region 71 (shown in dotted line) that this surface current is dynamic, therefore condense.
Then, in present embodiment, for lobus sinister sheet 23a, restriction is to the rotation of the opposition side (direction i.e. opened from the frontal of indoor set 1) of the side being configured with lobus sinister sheet drive division 25a.Similarly, for lobus dexter sheet 23b, restriction is to the rotation of the opposition side (direction i.e. opened from the frontal of indoor set 1) of the side being configured with lobus dexter sheet drive division 25b.Hereinafter enumerate object lesson to illustrate.
Fig. 8 (a) be represent lobus sinister sheet 23a relative to frontal to opposition side (from frontal direct-view for right side) the rotational angle Y1, lobus dexter sheet 23b of the side being configured with lobus sinister sheet drive division 25a relative to frontal to the figure of the state of opposition side (being left side from frontal direct-view) the rotational angle Y1 of the side being configured with lobus dexter sheet drive division 25b.
In the present embodiment, when as shown in Fig. 8 (a), lobus sinister sheet 23a and lobus dexter sheet 23b rotates, in the case of the condensation condition of regulation is set up, the rotation of lobus sinister sheet 23a is limited to angle Y2 from angle Y1.Same, the rotation of lobus dexter sheet 23b is also limited to Y2 from angle Y1.By such restriction, air-flow easily be positioned at left end lobus sinister sheet 23a side (close to the face of frontal) and be positioned at right-hand member lobus dexter sheet 23b side (close to the face of frontal) flowing.Thus, the lobus sinister sheet 23a being positioned at left end diminishes with the temperature difference on the respective two sides of the lobus dexter sheet 23b being positioned at right-hand member, therefore, it is possible to suppression is to the condensation of each blade.
It addition, angle Y1 is more than angle Y2 of the limited angular as regulation, therefore implements the angle correction control with suppression condensation, but in the case of angle Y1 is less than angle Y2, the probability of condensation diminishes, and therefore there is no need to be modified the control of angle.Additionally, angle Y2 is the value precomputed according to experiment etc., not unique value determined, it is possible to suitably change.
As it has been described above, in the present embodiment, when lobus sinister sheet 23a tilts to the opposition side of the side being configured with lobus sinister sheet drive division 25a, the angle that lobus sinister sheet 23a rotates is limited to the opposition side of the side being configured with lobus sinister sheet drive division 25a.Additionally, lobus dexter sheet 23b to the lopsidedness being configured with lobus dexter sheet drive division 25b time, limit lobus dexter sheet 23b to be configured with lobus dexter sheet drive division 25b side opposition side rotate angle.By such limiting rotating angle, it is possible to suppression is to the generation of the condensation of each blade self.
Then, the control of condensation during suppression pendulum wind pattern (Swing mode) is described.Generally carrying out air regulation operating according to the operation mode of regulation, one of them pattern is pendulum wind pattern.When putting wind pattern, blade centered by the central shaft of regulation to the left and right with the identical angle of timing rotation of regulation.The figure of one example of the state of lobus sinister sheet 23a when Fig. 9 (a) is to represent pendulum wind pattern.As shown in Fig. 9 (a), lobus sinister sheet 23a centered by central shaft 28a with regulation timing pendulum angle B to the left and right.Central shaft 28a passes through as lobus sinister sheet 23a and the fulcrum of the point of contact of left connection shaft 24a, and relative to frontal to side (being left side from frontal direct-view) the angle of inclination Z1 being configured with lobus sinister sheet drive division 25a.It addition, angle B is angle set in advance.
Central shaft is utilized remote control unit 30 directly to determine by user sometimes, is the most automatically determined as the direction at the people place detected by infrared ray sensor 4.Thus, according to the position of central shaft, when putting wind pattern, it is also possible to the cold air for blowdown firing cools down lobus sinister sheet drive division 25a by through hole 26a.Result condenses at lobus sinister sheet drive division 25a.
The generation of the condensation of blade drive division 25a to the left during in order to suppress to put wind pattern, present embodiment is controlled in the following manner.First, in the case of the condensation condition in regulation is set up, it is judged that whether angle Z1 of central shaft 28a is more than angle Z2 of the regulation predetermined.If more than angle Z2 that angle Z1 is regulation, then the mode for angle Z2 of regulation that tilts with central shaft 28a is modified.By this correction, lobus sinister sheet 23a, swings with angle B relative to frontal centered by the central shaft 28a of angle Z2 to the left and right.
By so carrying out the correction (by the adjustment in direction being tilted towards closing of central shaft 28a) of central shaft 28a relative to frontal, the amount of the air-flow blocked by lobus sinister sheet 23a reduces, and the amount of the air-flow therefore arriving lobus sinister sheet drive division 25a via through hole 26a also reduces.Thereby, it is possible to the cooling effect that suppression is to lobus sinister sheet drive division 25a, it is possible to suppress the generation of the condensation of blade drive division 25a to the left.It addition, angle Z2 can be the value identical with above-mentioned angle X2, it is also possible to for different values.Additionally, the pendulum wind pattern of lobus sinister sheet 23a is illustrated, but lobus dexter sheet 23b is carried out too to the correction of central shaft.I.e., in the case of the condensation condition specified when putting wind pattern is set up, in order to suppress the cooling effect to lobus dexter sheet 23b, the opposition side of the central axial side being configured with lobus dexter sheet drive division 25b of lobus dexter sheet 23b is revised (that is, by the adjustment in direction being tilted towards closing relative to frontal of central shaft).
Then, illustrate to combine lobus sinister sheet 23a and the control of lobus dexter sheet 23b of above-mentioned control.
Figure 10 (a) is the figure representing both lobus sinister sheet 23a and lobus dexter sheet 23b state of (being right side from frontal direct-view) angle of inclination W to the right.It addition, lobus sinister sheet 23a and lobus dexter sheet 23b is made up of multiple blades respectively, but as representing, the most only represent the lobus sinister sheet 23a of left end and the lobus dexter sheet 23b of right-hand member, described below.
Lobus sinister sheet 23a rotates to the opposition side of the side being configured with lobus sinister sheet drive division 25a.Thus, in the case of the condensation condition of regulation is set up, first determine whether that whether angle W of lobus sinister sheet 23a is more than angle Y2.In the case of angle W is more than angle Y2, it is modified in the way of the angle of lobus sinister sheet 23a becomes angle Y2.
On the other hand, lobus dexter sheet 23b is to the lopsidedness being configured with lobus dexter sheet drive division 25b.Thus, it is judged that whether angle W of lobus dexter sheet 23b is more than angle X2.In the case of angle W is more than angle X2, it is modified in the way of the angle of lobus dexter sheet 23b becomes angle X2.
As it has been described above, by making lobus sinister sheet 23a different with the angle correction of lobus dexter sheet 23b, it is possible to suppress the condensation to the lobus sinister sheet 23a being positioned at left end, and suppress the condensation of blade drive division 25b to the right.It addition, Figure 10 (a), (b) illustrate the situation that lobus sinister sheet 23a and lobus dexter sheet 23b right direction tilt, but it also is able to when left direction tilts be controlled based on same method.That is, when lobus sinister sheet 23a and lobus dexter sheet 23b left direction tilt, if the angle of lobus sinister sheet 23a is more than X2, it is modified in the way of becoming angle X2, if the angle of lobus dexter sheet 23b is more than Y2, is modified in the way of becoming angle Y2.
Further, in the present embodiment, lobus sinister sheet drive division 25a and lobus dexter sheet drive division 25b has motor and gear.When motor does not drives, a phase of motor (periodically) is applied DC voltage off and on.By applying such DC voltage, it is possible to the temperature of motor to be maintained more than condensation point, suppression condensation.It addition, use motor in the present embodiment but it also may for other motor.
Figure 11 is the figure representing the situation to the voltage that motor applies.In the present embodiment, in the case of the condensation condition of regulation is set up, in the case of motor is not with pendulum wind mode activated (i.e. left and right wind direction change blade 23 does not drives), a phase of motor is applied intermittently DC voltage (i.e. energising).
Specifically, when the condensation condition of regulation is set up, first apply DC voltage V (such as 14V) to motor, be continuously applied DC voltage V in the period of the motor ON time Ton (such as 4 seconds) of regulation.When through motor ON time Ton, the applying of voltage stops.After a stop, the period at motor Toff turn-off time (such as 6 seconds) does not apply DC voltage.Making this circulation is a cycle (such as 10 seconds), periodically repeats the conducting and disconnection carrying out applying to the voltage of motor.
After repeating above-mentioned circulation, in the case of the condensation condition of regulation is invalid, the voltage stopping the interval to motor applies.
By utilizing such control direction to make motor heating, it is possible to the generation of suppression condensation.Additionally, by conducting being periodically switched and carrying out the energising to motor with disconnecting, it is possible to make the temperature of motor increase not damaging the control of reliability.I.e., it is possible to the temperature of suppression motor becomes too high, therefore, it is possible to suppression durability suffers damage, and the rising of power consumption can be suppressed.
As it has been described above, in the present embodiment, by revising the angle of left and right wind direction change blade, it is possible to suppress the condensation to the drive division driving left and right wind direction change blade, and also be able to suppress the condensation of left and right wind direction change blade self.Additionally, in the present embodiment, left and right vane drive mechanism is arranged in both sides, therefore, it is possible to concurrently and independently carry out the control of the air-flow of left direction and right direction, it is possible to blow to all directions.It addition, also be able to apply the present invention in the case of left and right vane drive mechanism is arranged in one side.
The present invention can not only be applied to the above-mentioned air conditioner connecting an indoor set on an off-premises station, it is also possible to is applied on an off-premises station connect the air conditioner of the multi-type having multiple stage indoor set.
It addition, by the arbitrary embodiment in appropriately combined above-mentioned various embodiments, it is possible to reach the effect each being had.
Sufficiently illustrate the present invention above by reference to accompanying drawing and based on preferred implementation, but those skilled in the art can specify various changes and modifications.As long as the scope of the present invention that these deformation and amendment are limited less than claim, just it is construed as comprising within the scope of the invention.
